Level 2 Diagnostics
Level 2 diagnostics run during normal printer operation. When the following conditions
occur, the printer automatically turns off the appropriate motors and disables printing to
prevent damage:
• Paper out, cover off, or knife unable to home
•
Printhead too hot or voltages out of range
The lights on the operator panel will signal when these conditions occur as well as indicate
what state or mode the printer is in. See “Troubleshooting” later in this book for more
information.
Level 3 Diagnostics
Level 3 diagnostics keep track of the following tallies and prints them on the receipt during
the print test. See the sample test printout in “Testing the Printer” in Chapter 2.
• Number of lines printed
• Number of knife cuts
• Number of hours the printer has been on
